摘要：

The important parameters in gas-solid reactions can be determined simultaneously, under non-steady-state conditions using reversed-flow gas chromatography. A very simple experimental arrangement is required, with a slightly modified gas chromatograph. The distorted diffusion band obtained experimentally can be analysed mathematically giving, for the gas reactant, the values of adsorption, reaction and desorption rate constants, the overall mass transfer coefficients in the gas and in the solid and the adsorption equilibrium constant. All these parameters were determined at various temperatures for the reaction of sulphur dioxide with pieces of marble of two sizes, using two different air flow-rates.
